Advanced Anchor Best Practices

Efficient, production-grade Anchor 0.32.1 programs combine optimization with unchanged security bar.

How to Use This List

• Use after basics, accounts, and CPI sections are solid.
• Profile before applying zero_copy or native CPI.
• Security review still required.

A - Performance

• Profile CU on LiteSVM before mainnet data-driven optimization only.
• Store bumps and prefer zero_copy for large fixed state when profiling justifies.
• Strip debug features from mainnet release builds smaller .so and lower CU.

B - Advanced patterns

• Document remaining_accounts protocols not in IDL.
• Plan realloc/migrations with version bytes before growing accounts.
• Prefer declare_program! over manual invoke when IDL exists.
• Keep custom account types rare and tested default to Account<T>.
